Rumple was adamant about knowing the name of SW and PC’s unborn baby’s name, we now know it was because after the curse, he would need to hear the name in order to get his memory back, which he did. He used the drop of true love on the curse when he wrote it. He referred to that as a ‘safety valve’. Could be, that’s what he did in order to be able to find the child of the Savior, Emma…used some sort of ‘safety valve’.
